Based on his experience, the author assumes that merchants and traders are not immune to injustice. It appears that these figures have never enjoyed a good reputation. Still, the problem lies not in being a merchant, but in letting oneself be driven by the desire for profit (27:1). However, the key to avoiding injustice is given by the author in 27:3: one must be steadfast and diligent in fearing the Lord. Thus, the fear of the Lord is not only the beginning of wisdom but also the fundamental principle of justice.
